It's really difficult to be broke these days. When one of your properties breaks down, you are forever conflicted with the indecision of whether or not it is worthy of a repair or not. in the case of your car, for example, it is really worth all your extra cash to make repairs possible for your broken car audio? Is having a functioning car audio really that important to you? Or perhaps you can do without it and are okay with an alternative instead? If you are not a hardcore auto enthusiast, perhaps you can live with one of these alternatives.
Headphones or earphones
These are already modern times after all. I'm sure you're stuck with your gadgets 24 hours a day, 7 days a week. Even without the usual group of gadgets (smartphone, laptop, tablet, etc.) found in a yuppie or even an adult, you are probably enjoying a good smartphone or two. Music players are never absent in these gadgets. And so, you can choose to ignore that broken car audio and just wear your headphone or earphone like you do at the other times of the day. There's really no difference in that. You can still listen to music. If you want to listen to news, all you have to do is switch to radio.
Musical instrument
Yes, your gadgets are the obvious choice for your source of music in your car. However, in case you are feeling existential at the moment for no reason (or whatever reason you may have), you can carry your favorite instrument inside your car and play it every time you stop for something on the road. Of course, you can't bring a piano, a cello, or any oversized instrument. That will be ridiculous. Perhaps this is the right time to practice your guitar and ukulele skills. A harmonica perhaps? Or, a flute. What do you think?
Your own voice
I'm only providing this option because it's available. Why can't you enjoy your own voice in the privacy of your own car? Whether you have a good voice or not is out of the question. You can do this when you are bored. This can also be classified as one of your existential expressions to the world. Okay, I know that's downright weird. But you don't know when you will be feeling that way. And what if you suddenly feel that while driving?
Losing a car part is unfortunate indeed. To a car enthusiast, a broken car audio is a big deal. If you are not that much of a car lover though, then perhaps this incident is just sad. But, at least it's just your car audio. What would you do if your car engine broke or your windshield crashed? Now, those damages demand repair, unless you decide to just ride the subway in the foreseeable future. Anyway, it's cool to be thinking of alternative ways to do something. Doing the same thing every day is rather boring, don't you think? Plus, you can train your mind to think of quick solutions when you are in a jam.
